If a 8K (mirror) stainless steel sheet is scratched by accident, how can I rescue it? If the scratch is not very serious, during mirror polishing, you can slow down the feed roller speed and lower the grinding head to make the scratched area as smooth as possible.

It is generally understood that there are several situations where mirror stainless steel scratches appear:

The first is that the sheet is scratched before processing, it is just not obvious, this requires judging the severity of the scratch. If the scratched area and scratched depth have exceeded the customer's acceptance of the final product effect, then the sheet that meets the requirements should be replaced. That is, the inspection of the processing operator is very important.

The second is that the sheet has been mirror-finished, but it was accidentally scratched during the filming process. There are many kinds of such scratches, such as: point scratches, linear scratches, and large-area scratches. Point-like scratches, regardless of the depth, can be repaired by argon arc welding, then polished with a grinder, and then processed by mirror polishing equipment for two or more times. This problem can basically be solved.

How to deal with scratches on stainless steel mirror sheet?

If it is repaired on the bright surface, the polishing method can be used, and the polishing wheel of different meshes can be repeatedly polished. In general, sandblasting is used for matte surface repair, which requires special equipment. If the wire drawing panel has been done in the early stage, special equipment is also required. No matter which method is used, the surface must be passivated at the end. It is judged as a slight scratch. If it is a mirror surface, you can polish the stainless steel surface with polishing wax. If it is a wire drawing, you can use a wire drawing machine to wire the stainless steel surface.

Then there are linear scratches, which are what we call scratches. It is relatively difficult to deal with scratches. Shallow scratches can be solved by the above method (slow down the speed of the feed roller and lower the grinding head). Deep scratches are not easy to handle. Lishun stainless steel recommends that you try to avoid scratches when processing and cutting the mirror panel material.

In addition, when talking about large-scale scratches and scratches, there are two types of scratches, and the treatment methods are the same as above.

If it is the second type of scratch, it is more difficult. Because this kind of secondary scratches should be avoided as much as possible. It is recommended that you reduce or avoid the possibility of scratching the mirror panel by the following methods: sticking a protective film on the surface of the board, packaging the board with a wooden frame, padding the board or plastic board on the board, packing the whole with waterproof paper, and expressing "protection" on the board or packaging surface Good surface, don’t scratch” and other words. If the finished mirror stainless steel plate has scratches, it can basically be done according to the method mentioned above. If it is a semi-finished equipment, and the surface is mirrored with scratches, you need to use a variety of polishing equipment; such as a hand-held polishing machine that can replace multiple polishing wheels to achieve a better repair effect.
